The single-acting clamping module SCHUNK VERO-S NSE3 138-V4 increases the flexibility in clamping pallets with just one clamping pin: While the pallet alignment on conventional single clamping modules, which are equipped with an anti-twist protection is precisely defined, pallets on the VERO-S NSE3 138-V4 can be rotated in 90° increments. This allows to vary the position of the pallet assembly by 90°, 180° or 270°. The anti-twist protection takes place by means of two axially flexible, but tangentially rigid elements inside the clamping module, which position the pallet. The single clamping module has a patented dual stoke system, and is part of the extensive SCHUNK VERO-S modular system, which enables more than 1,000 possible combinations for efficient workpiece clamping. The standard clamping module is suitable for the manual or automated mounting of clamping pallets in the format 159 mm x 159 mm. On option, it can be equipped with a spring-actuated cone seal that automatically locks the module’s interface, as soon as the pallet is lifted out with the clamping pin. Without changing the height, it locks the last gateway of the otherwise completely sealed module.

Pull-down force of 28,000 N ensures a high rigidity

With activated turbo function, the dimensionally stable single-clamping modules have an enormous pull-down force of 28,000 N. Mounting and positioning take place via a short taper with a repeat accuracy of < 0.005 mm. This ensures maximum precision even in the most demanding applications. Due to the conical fitting, the clamping pins can also be joined into the modules eccentrically, making this process incredibly easy. The actual clamping takes place without any external energy supply via spring force; it is form-fit and self-retaining. The workpieces remain safely clamped in the case of a sudden pressure drop in the air system. A pneumatic system pressure of 6 bar is sufficient to open the clamping modules. Depending on the thread diameter, the used clamping pins have holding forces of 35,000 N (M10), 50,000 N (M12), or 75,000 N (M16). All components, such as base bodies, clamping pins, and clamping slide, are made of hardened stainless steel, making them absolutely corrosion-resistant and long-lasting.
